The company has reportedly confirmed the layoffs, though did not comment on numbers: "We have let a number of consultants and a few full-time employees go recently," said comms director Kim Fai Kok, "which is natural to any company in a high growth stage."

Kim Fai Kok did not immediately respond to a request from Business Insider for comment about the size of the layoffs and the financial state of the company.

Launched in 2009, Truecaller builds an Android app that helps users verify who is contacting them, flagging up potentially spammy numbers. In July 2015, TechCrunch reports the startup, based in Stockholm, was raising $100 million (£66 million) at a valuation of $1 billion (£660 million) — making it a fabled "unicorn" startup.

The company also raised $60 million (£39 million) in 2014, with investors including Kleiner Perkins Caufield & Byers, and Atomico.
